Taking out en-suite??

[strainers1]

Hello, im helping my cousin take out an en-suite in his house as he wants to convert this to a walk in wardrode.
My problem is how do i cap the waste's for toilet,shower and basin??
All off these wastes go down under floor,none of them go straight to outside wall.
Is there stop ends I could get for these so that the pipes could stay under floor incase through time they wanted to reconnect or new owner wanted to connect?

Any help would be great,thanks

Thanks. I got caps at local plumb centre there. My only worry was smell coming back up 4inch toilet waste but told with cap this won't happen
